Unit 7 (see below) requires you to investigate 'interactive media' as part of your course. Obviously, this isn't the main focus of VFX and Animation, so you meet this requirement through the making of your coursework website.
This short project is also a great way to get you used to how projects are structured for UAL assessment. The process of research leading to planning, leading to production, supported by evaluation and reflection, is at the heart of how UAL conceptualises creative media production and it's embedded throughout the course.
Units 1 and 2 (below) are covered in part by your formative projects, and in part by your theory work.
